Description:
X-rays from a region containing the nucleus of the type 1 Seyfert galaxy 3C 120 have been detected using the rotating modulation collimator on board the SAS-3 X-ray observatory. The error circle has a 95% error radius of 1.0 arcmin. The measured X-ray (2-10 keV) flux is 5.4 by 10 to the -11th power erg/s per sq cm. The corresponding luminosity is 2.3 by 10 to the 44th power erg/s for the source at 200 Mpc. Synchrotron-Compton and hot plasma models are discussed.
